This document describes a journey through scales of size from microcosm to macrocosm and back again. It starts at 1 meter and increases distances traveled by factors of 10, reaching millions of light years out into space. It then returns, decreasing distances by factors of 10 down to the scale of atoms and subatomic particles like quarks. The key point is that the same laws of physics apply at all scales, and this perspective helps us understand how little is still known about the universe.
